Anime Schoolgirl Guitarist on Stage

Create a polished anime-style vertical illustration of {argument name="character name" default="a teenage schoolgirl guitarist"} standing on a dark concert stage under soft overhead spotlights. She has {argument name="hair color" default="glossy black"} hair in a short bob with straight blunt bangs and a side ponytail she is tying up with both arms raised, pale skin, large muted gray eyes, and a small blue hair tie held in her mouth, giving a shy focused expression. She wears a crisp white Japanese sailor-style school uniform top with short sleeves and a bright turquoise neckerchief, paired with a high-waisted dark navy pleated skirt. A black guitar strap crosses her shoulder, holding a bright {argument name="guitar color" default="turquoise blue"} electric guitar with a white pickguard, chrome hardware, maple neck, and cable plugged in, angled diagonally across her body from lower left to upper right. Place one silver vocal microphone on a black stand to her left, and one black Marshall-style guitar amplifier with cream control panel to her right in the background. Use a mostly black stage backdrop with tiny floating dust-like white specks, dramatic rim lighting, clean cel-shaded anime rendering, delicate highlights on hair and guitar, realistic instrument details, soft shadows, and a slightly low portrait composition focused on the character from thighs up.
